Raimondi Levelling System (R.L.S.) is a revolution in the tile setting. In addition to ensuring the proper leveling of tiles, this system helps to speed up the tile setting process. R.L.S. is strongly recommended when installing ﬂexible, large format, heavy or low-thickness tiles. R.L.S. is made up of three elements: clips (spacers), wedges and pliers. Clips are available in two different versions: for tiles from 3 up to 12 mm thickness (1/8” - 1/2”); for tiles from 12 up to 20 mm thickness (1/2” - 3/4”). The wedge works for both clip sizes and it is re-usable virtually forever.
